Roll remaining disk of dough into 12-inch round. With floured pastry wheel or knife, cut dough into 1-inch-wide strips. Brush edge of bottom crust with some milk. Place half of strips, about 3/4 inch apart, across top of pie. Place remaining strips perpendicular to first strips or use to weave a lattice. Trim ends, leaving 1-inch overhang. Press strip ends onto edge of bottom crust to seal. Turn overhang up and over ends of strips; pinch to seal and make a high fluted edge. Brush lattice with remaining milk; sprinkle with remaining 2 teaspoons sugar.

Place pie plate on hot foil-lined cookie sheet. Bake pie 20 minutes. Reset oven control to 375 degrees F. Bake pie 1 hour and 30 minutes longer or until filling bubbles and crust is deep golden brown. Cover pie loosely with foil after first hour of total baking time to prevent overbrowning. Cool pie on wire rack about 2 hours to serve warm, or cool completely to serve later.
